Abstract (en)
A sealant injector for use in repair is provided with a sealant nozzle (2) formed in a forward end of an injector body (1). A piston (6) is slidably fitted in the injector body (1), and cooperates with the forward end of the injector body (1) to define therebetween a sealant chamber (7) capable of being filled with sealant. A coil spring (8) is arranged within the injector body (1), and is provided with such a shape memory effect that when heated, the coil spring (8) biases the piston (6) toward the forward end of the injector body (1) to inject the sealant through the sealant nozzle (2). A heating unit (9, 10; 9, 11; 14) is adapted to be associated with the injector body (1), for heating the coil spring (8).
